Application filed June 10, 1927. Serial No. 197,917.

This invention relates to door checks and the general object of the invention is to provideba device of the character set forth have ing means arranged in the path of a door and cooperating with relative means for retarding the closing of the door so as to prevent slamming thereof but allowing the ldoor to close gently with minimum sound and vibration.

A further object of the invention is to provide a door check that is easy to apply, extremely simple in construction, inexpensive to manufacture, is strong and sturdy, and efficient in operation and service.

This invention also consists in certain other features of construction and in the con'ibination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and'specilically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanyingdrawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a fragmentary perspective view illustrating the application oi' my check to the frame of a door.

Figure 2 is a face view of the check per se with the cover removed and showing the parts in normal positiom l L Figure 3 is a similar view with the pares in operative position and showing the door in dotted lines. n p

Figure 4 is a sectional view taken approximately on line 4-4 of Figure 2.

The case 1, and the cover 2, constitute the casing in which my check mechanism is housed. Upon the pin il, is pivotally secured a hanger 5, at the lower end of which is suspended a balanced catch 8, pivoted on a pin 9. The catch 8 .is shown being substantially rectangular in formation and the .pin 9p eX- tends through a depending projection or the hanger and through the side walls ot the catch which is provided with a reduced end shaped to give the catch a substantially p awi like forni.` Below the balanced catch is a curved block 10, into which notches are cut on its upper surface. rPhe device is attached to the door j amb 11 by means-otl screws 3 and the door stop 13 is cut away to permit the casing to be fastened to the jamb 11, flush with the stop 13.

The hanger swings free on the pin l, and sutlicient clearance is provided between the balanced catch 8 and the block 10, to permit the hanger 5, to be pushed back, flush with the rear wall of the vcasing 1, if done slowly so as to not cause the catch to swing on its pivot. The catch 8 is however so balanced that when the door l2 is slamn'ied against an arm 111 which normally extends through an opening formed in the casing and is included in the hanger 5, the inertia of the balanced catch 8, impels it to dip and thereby catch the reduced end in the notches in the block and stop the door before it slams against the door stop 13. Upon the rebound, the hanger@ and the balanced catch 8, swing back to original position and when the door 1Q, is gently closed against it, the reduced end passesthe` notches in the block 10, without engaging and the door closes against the stop 13,13. An arm 15 is also included in the hanger and extends rearwardly in opposed relation with respect to the arm 1li. The arms may have their ends grooved as at 16, to accommodate the tongues 17 of rubber facings 18, which are secured to the arms by the tongue and groove connections asshown. The arms are slightly tapered and together with the portion which receives the pin 4t gives the hanger the form of an inverted T.

I claim:

1. door check of the. character described comprising a casing having an opening formed therein, a hanger pivotally secured in said casing, means formed with said hanger and normally arranged through said opening to be arranged in the path of a door, notched means arranged in said casing and means pivotally secured to the hanger and coope ating with the notched means.

2. A 'door cheek of the character described comprising a casing, a suiistantially T-shaped hanger arranged in inverted position therein, means for pivotally securing the hanger in said easing, a depending projection included in said hanger, a catch pivotaliy secured to the projection, a block arranged in said casing below the catch and being provided with notches cooperating with said catch, and said casing being provided with an opening to aceomn'iodate a portion ofsaid hanger for the purpose specified. i

A door check ofthe character described comprising a casing, a hanger pivotally secured in said casing,opposed arms included in said hanger and being provided with grooves in their ends, resilient means secured in said grooves, a projection included in said PATENT orifice.g
